This seems to be related to a missing optimized code path for SRCINVERT in
dlls/winex11.drv/bitblt.c,BITBLT_InternalStretchBlt(). Once I add SRCINVERT
case to any existing case statements (say DSTINVERT) any slowdown in mouse
movements goes away, though painting apparently becomes wrong. Now what needs
to be done is a proper implementation of SRCINVERT in X11 graphics terms.
I'm not an expert in that, any takers?
